Abstract

Procédé d'établissement d'une spécification de dimensionnement d'un équipement destiné à être monté sur une structure de turbomachine telle qu'un carter, le procédé comprenant les étapes suivantes : - sélectionner (S8) un incident susceptible de se produire sur la structure, tel que la perte d'un élément de rotor de la turbomachine ; - simuler (S14) la présence de l'équipement sur la structure, en un point d'attache, au moyen d'un oscillateur mécanique ayant au moins une fréquence propre (f0) et au moins un taux d'amortissement (?) ; - faire varier la fréquence propre et/ou le taux d'amortissement selon au moins deux valeurs ; - déterminer (S18) une accélération de dimensionnement de l'oscillateur mécanique en réponse à l'incident pour chacune desdites valeurs de la fréquence propre et du taux d'amortissement ; - délivrer (S20) la spécification comprenant les accélérations de dimensionnement et les valeurs de fréquence propre et de taux d'amortissement correspondantes.
